SiS reveal new chipset lineup
The single-chip 680-series, consists of five different variants. Catering for the high-end user is the 680SCD which supports 1333MHz FSB Penryn processors, DDR2-800 and 1066 memory support and a single PCIe x16 slot.
The mainstream SiS 680SCE and 680SCH are identical except for FSB support. The 680SCE supports 1333 MHz FSB while the 680SCH is limited to 1066 MHz. Setting them apart from the 680SCD is the integrated Mirage 4 graphics core which supports HDMI, DirectX 10 and H.264 and VC-1 acceleration.
The low end variants, dubbed the 680SCP and 680SCL drop memory support to as low as DDR2-800, and support different FSB’s.
SiS plans to support DDR3 memory with its dual-chip designs. The upcoming 665, 673FX and 673 add DDR3-1333 memory support to an identical feature list as the single-chip parts. However, the upcoming SiS 665, 673FX and 673 will have a new 969 south bridge to pair up with. The new SiS 969 features ten USB 2.0, one PATA133 channel, four SATA 3.0Gbps with RAID 0, 1, 5, JBOD and 0+1, one PCIe x16, four PCIe x1 and high definition audio support. The SiS 969 will also accept a trusted platform 1.2 module as well.
